Great Britain October 14, 194-6 4 Claims. *1 This invention relates in general'to aslicing machine of the so-called gravity feed-class,' as disclosed in application Serial No. 766925, filed 'August4i,194=7, wherein 'theslicing machine is crossed'by an inclined carrier down which-the substance to'be sliced moves step by step, under the influence ofgravity, and under 'thecontrol of a slice thickness gauge, to a rotary'cutting knife.

More specifically, the invention relates "to a carriage constructionior slicing machines of the type disclosed in the copending application-filed August 4,1947, SerialNo. 766,026, wherein-there is disclosed a slicing. machine" having a reciprocatingcarriage that comprises two components which aredetachably interconnected to form a rigid structuralunit; the upper component being the, substance carrier and the lower component being a support WhiChl'lS 'reciprocable along one or more guides ,On thema'chinejframe, being constrainedhbyv said guide or. guides to longitudinal movement; that .is to say, the support component is constrained against movement relative to the slicing plane.

The present invention is an improvement of the stuctule. disclosedminthe. aforesaid, copending application,.-Serial,,.Number 766,026, and as discloseclspecifically in the otheraforementioned application, Serial No.1766,025,.filed.August .4,

According to the presentinvention, ina slic- 1 ing machine of. the. classstatedthe gravity. feed carrier is .connected to anlongitudinallyn guided support by. male and female. joint members and .which isdisconnectedbyathe act..,of lifting the .carrier.

Further, according to. the presentinvention, in a; slicing machineof: .the class stated, the gravity feed carrier is connected to a. longitudinally guided support by a'mainpin-and-socket joint with which ,is associated an auxiliary ,joint a'dapted to prevent rotational movement. of the carrier in relation to the support about the axis of the main joint, the arrangement being such that. the carrier can be disconnected by the-act of lifting it from the support.

'In anexample, the gravity feed carrier has two dependent pins, the main-one of thembeing along; pin; and the longitudinally guided support has asocket into hich the main pin fits and a fork-like member with a slot into which the auxiliary pin fits. The carrier comprises an inclined trough which fits upon a holder formed with two bosses, both facing vertically downwards. The two dependent pins are secured to these bosses, and both pins are vertical. The

2 boss or the main pinis arranged in-a:position where it can "best take-the--weight of thecarrier when. loaded. The support 'isa bracket -incorporated in alongitudinally guided reciprocable carriage; and-the-b acket is'iormed with apillar and is providedwith a-han'dle by means of which the operatorcanpush-and 'pull the-carriage.

Thepillar is asocket, having along'vertical'hole. 'The' top portion of this holeds-formedas-an upper bearing for the ;-main pin,-and theiower end of the hole, formedgas a foot-stepbearing for the. foot of" themain pin. n holdingdown screw at the bottom of the'h'ole-has ahead-upon which the slightly tapered foot of' thema-in pin rests. The pillar has a lateral: arm towhich; is

secured a horizontal two-pronged fork, a rounded slot being formed between the prongs to engage the-auxiliary pin. The boss of thispin is'ldished out so that the fork is enclosed by the boss.

The arrangement is. such thatithe maingjoint takes the weight of the carrierand the substance I thereon, whereas the main and auxiliaryfjoints cooperate to takethe forces, due toithe reciprocating motion ofthe carriage andfdueito' thefslicingv action of the knife, the auxiliary joint preventing rotational motion of'the carrier, about the axis of the. main pin.

.The carrier is disconnectedTfromthesrest,of thecarriage. simply by lifting it verticallyjfrom the support, therebeing no, need forflthesu'se of tools.

.The. accompanying drawingfillustratesla selected embodiment of a, food trough or. carriage which .is adapted to be reciprocatedgalong a rectilinear .path and has, a .troughportion which .is. disconprises a base I which houses alongitudi-nalrslide bar 2 to guide a carriage-memberii which extends beneath or througha side wallof the base. .A guide rod 4 is also positioned below thelbase, there being a roller 5.;on the carriage member .3 so that the carriage-memberwill be guidedand supported by the slide bar 2-and theguiderod-L A pillar or standard 6 is connected to the carriage member 3 and extends upwardly and vertically therefrom. This pillar or standard 6 may be made an integral part of the carriage member 3 but is preferably made as a separate unit and is detachably connected to the said carriage member. A knob or handle operating member I is connected rigidly to the standard 6 to shift the carriage member and standard longitudinally in a rectilinear path. The standard or pillar 6 has a vertical opening 8 formed therein to receive a pin 9 on a V-shaped trough ID. The pin 9 is shown connected to a boss II on the V-shaped trough, but the pin 9 may be fixed in the vertical opening 8 in the standard and received in an aligned cooperating vertical opening 12 in the boss II. It is preferable, however, that the pin 9 be secured to the boss and extend downwardly in the vertical opening 8, as clearly shown in the drawing. The bottom of the pin 9 may be made non-circular at its bottom end to fit in a cooperating non-circular opening at the bottom of the vertical opening 8. The trough I is adapted to be reciprocated longitudinally along a rectilinear path so that substance on the trough l0 may be cut by a circular rotating slicing knife l3.

The trough ID has a second boss I4 rigidly secured thereto and extending downwardly parallel with the boss II but spaced therefrom and in a different horizontal plane. The standard 6 has an extension l extending inwardly and adjacent the second boss I4. This extension 15 has a member [6 rigidly secured thereto in any suitable manner such as by fastening screws [1. The end of the member I6 is provided with a bifurcated end l8 providing a slot I9. This slot i9 is adapted to receive a pin fixed in a bore in the second boss 14, the bottom of the extension l5 and the bottom of the second boss I4 bein recessed, as clearly shown in Fig. 2, to receive the member l6 so as to overcome any projecting parts and to make the bottom of the member l6 flush or substantially flush with the bottom surfaces of the second boss M and the extension I5.

The construction is such that the V-shaped trough I0 may be removed by merely raising the food trough upwardly so that it will become detached from the supporting pin 9 and the second supporting pin 20 and its cooperating member IS. The member I6 and its disconnectable connection with the pin 20 prevents any pivotal movement of the food trough I0 about the vertical pin 9. The pin 9 absorbs the majority of the weight and strain as the majority of the weight will be applied to the boss II and the upper part of the standard or pillar 6. The pin 20 and the bifurcated member IE will also assume some of the weight, but the main purpose of these latter elements is to prevent shiftable movement of the food trough ID with respect to the standard 6.

The carriage member or food trough is adapted to be slid back to and fro in a rectilinear path by merely grasping the knob 1 so as to bring substance on the V-shaped trough I0 past the cutting plane of the knife l3. The handle is grasped, and the carriage member 3 and its cooperating V-shaped trough is reciprocated by pushing or pulling the handle or knob 1.

The invention provides a relatively simple device which permits the food trough to be removed from its cooperating support or standard by merely lifting it upwardly without the use of tools.
